Detailed Description

The class facilities generation and storage of conversion FixIts.

Hints for new conversions are added using TryToFixConversion method. The default type conversion checker can be reset.

Member Data Documentation

◆ CompareTypes

TypeComparisonFuncTy clang::ConversionFixItGenerator::CompareTypes

The type comparison function used to decide if expression FromExpr of type FromTy can be converted to ToTy.

For example, one could check if an implicit conversion exists. Returns true if comparison exists.

◆ Hints

std::vector<FixItHint> clang::ConversionFixItGenerator::Hints

The list of Hints generated so far.

Definition at line 41 of file SemaFixItUtils.h.

Referenced by clear(), clang::Sema::DiagnoseAssignmentResult(), DiagnoseBadConversion(), and tryToFixConversion().

◆ Kind

OverloadFixItKind clang::ConversionFixItGenerator::Kind

The type of fix applied.

If multiple conversions are fixed, corresponds to the kid of the very first conversion.

Definition at line 49 of file SemaFixItUtils.h.

Referenced by clang::Sema::DiagnoseAssignmentResult(), DiagnoseBadConversion(), and tryToFixConversion().

◆ NumConversionsFixed

unsigned clang::ConversionFixItGenerator::NumConversionsFixed

The number of Conversions fixed.

This can be different from the size of the Hints vector since we allow multiple FixIts per conversion.
